For type 1 and type 2, please follow these steps to identify the problem:

Please check if there is any damage on the touch screen and touch screen cable.

Make sure the power adapter and touch screen are connected to the controller properly, and restart the machine. Check if the problem persists.

Please shake both sides of the touch screen cable. If the touch screen could resume to normal transitorily, please fill in the warranty request, and attach a video which can show the problem.

Connect the machine to your computer, and start a new printing using Snapmaker3D or Snapmakerjs. If the machine could print properly, there is something wrong with the touch screen. Please fill in the warranty request, and describe the problem and everything you have tried to identify the problem.

For type 3 and type 4, please fill in the warranty request, and attach several pictures or a short video of the problem.
